“…In our present sample, evening chronotype was associated with greater symptoms of depression compared to intermediate and morning chronotype. The association between chronotype and depression is well documented in the literature (Facer-Childs et al, 2019;Üzer & Yücens, 2020;Zhou et al, 2021). Research has postulated that the connection between chronotype and mood may be partially due to evening types' reduced exposure to light (Gao et al, 2019).…”

Summary Chronotype is related to mental health, with evening chronotypes being more susceptible to psychological disorders than intermediate and morning types. The present study investigated the relationship between chronotype, mental health, sleep quality, and social support in Canadian young adults. We surveyed 3160 university students aged 18–35 years. Participants completed the Morningness–Eveningness Questionnaire, the Hospital Anxiety and Depression Scale, the Mindful Attention Awareness Scale, the Pittsburgh Sleep Quality Index, and the Medical Outcomes Study – Social Support Survey. We conducted Bonferroni‐corrected one‐way analyses of covariance with post hoc paired comparisons to determine the relationship between the aforementioned variables, with age and sex as covariates. We further looked at the moderation of social support on the relationship between chronotype and sleep quality. Overall, 55%, 36% and 9% of participants were classified as intermediate, evening and morning types, respectively. There was a significant difference between chronotype on levels of depression, anxiety, and sleep quality, with evening types reporting more severe symptomology than morning‐types and intermediate types. Morning types reported greater levels of overall social support and mindfulness. Evening types reported the lowest levels of all types of social support. Social support did not moderate the relationship between chronotype and sleep quality. This study further demonstrates the association between worse psychological well‐being and eveningness and between more social support, and mindfulness in morning chronotype young adults. Education and intervention are warranted to help evening chronotypes manage the potential negative features of their circadian rhythm, as well as to cultivate a greater sense of social support and mindfulness.

“…Recent studies with smaller samples of adults have demonstrated similar mediating effects of sleep, where poor sleep quality at least partly mediates the association of eveningness with depressive symptoms in healthy individuals (Horne et al, 2019; Van den Berg et al, 2018; Zhou et al, 2020) as well as in major‐depressive disorder (Selvi et al, 2018) or bipolar disorder (Caruso et al, 2020). There are also few exceptions, where the mediating effect of sleep quality on depressive symptoms was not significant in young healthy adults (Lin et al, 2020; Üzer & Yücens, 2020).…”

Background Epidemiological data show that having the eveningness associates with poor mental health. For preventive measures it is important to know which underlying factors mediate these associations and the burden posed to public health. This study examines at a population‐based level, whether (1) circadian type and the sleep‐wake behavior‐based phase entrainment similarly associate with mental health problems, (2) there are differences in hospital treatments due to mental disorders between chronotypes, and (3) the association of chronotype with mental health is mediated by insufficient sleep. Methods The study sample (N = 18,039) consisted of population‐based sample of Finnish adults, aged 25–74 years, with information on their circadian type and sleep patterns, mental health symptoms, and diagnosis as reported in a health examination survey, as well as hospital treatments as recorded on the national Hospital Discharge Register. Results All the mental health symptoms, diagnoses and hospital treatments were more pronounced among Evening‐types, especially when assessed by circadian type. Insufficient sleep mediated most but not all of the associations between eveningness and mental health. Conclusions Eveningness does not increase mental health risks only on symptom or diagnosis level, but also on hospital admission level. A higher prevalence of insufficient sleep among the Evening‐types elevates the risk and severity for many of the mental health outcomes. Improving the sleep among Evening‐types could help to improve their mental health prospective and ease the health care burden.

“…A large cohort study indicated that the association between evening chronotype and MMD could not be fully explained by sleep problems, such as insomnia and inadequate sleep duration ( Antypa et al, 2016 ). According to mediation analysis, hopelessness, defined as negative expectations for the future and core symptoms of MDD, mediates the relationship between evening chronotype and depressive symptoms, but not sleep quality ( Uzer and Yucens, 2020a ). Taken together, although there were conflicting results regarding the relationship between psychiatric disorders, chronotype, and sleep disorders, the general view is that evening chronotype is an independent risk factor for psychiatric disorders, especially depressive disorders, in which sleep disorders show a partially or fully mediating effect.…”

Chronotype, circadian rhythm, and psychiatric disorders: Recent evidence and potential mechanisms

et al. 2022

View full text Add to dashboard Cite

The circadian rhythm is crucial for physiological and behavioral functions. Chronotype, which represents individual preferences for activity and performance, is associated with human health issues, particularly psychiatric disorders. This narrative review, which focuses on the relationship between chronotype and mental disorders, provides an insight into the potential mechanism. Recent evidence indicates that (1) the evening chronotype is a risk factor for depressive disorders and substance use disorders, whereas the morning chronotype is a protective factor. (2) Evening chronotype individuals with bipolar disorder tend to have more severe symptoms and comorbidities. (3) The evening chronotype is only related to anxiety symptoms. (4) The relationship between chronotype and schizophrenia remains unclear, despite increasing evidence on their link. (5) The evening chronotype is significantly associated with eating disorders, with the majority of studies have focused on binge eating disorders. Furthermore, the underlying mechanisms or influence factors are described in detail, including clock genes, brain characteristics, neuroendocrinology, the light/dark cycle, social factors, psychological factors, and sleep disorders. These findings provide the latest evidence on chronotypes and psychiatric disorders and serve as a valuable reference for researchers.
